2. The device of claim 1 , further comprising two or more thin-film transistors, wherein each of said two or more thin-film transistors comprises one or more active-channel regions, and wherein each of said one or more active-channel regions comprises at least one of the first or second rectangular crystalline regions.
3. The device of claim 2 , further comprising an integrated circuit which comprises said two or more thin-film transistors.
4. The device of claim 2 , wherein said device is a liquid-crystal display device which comprises said two or more thin-film transistors.
5. The device of claim 4 , wherein said two or more thin-film transistors are pixel-controller thin-film transistors.
6. The device of claim 2 , wherein said device is a liquid-crystal display device which comprises a pixel-driver integrated circuit which comprises said two or more thin-film transistors.
7. The device of claim 1 , wherein the supporting substrate comprises a glass substrate, wherein said semiconductor film is formed on the glass substrate.
8. The device of claim 1 , wherein the supporting substrate comprises a substantially planar substrate, wherein said semiconductor film is formed on the substantially planar substrate.
9. A device on a supporting substrate, comprising: a semiconductor film, including: two or more rectangular crystalline regions, wherein each of said two or more rectangular crystalline regions abuts at least one other of said two or more rectangular crystalline regions and wherein each of said two or more rectangular crystalline regions comprises one single crystal region having a width dimension up to approximately 5 micrometers, wherein the two or more rectangular crystalline regions have long directionally controlled grains and long grain boundaries, and wherein the each of said two or more rectangular crystalline regions abuts at least one other of said two or more rectangular crystalline regions along a respective long grain boundary and wherein each of said two or more rectangular crystalline regions are absent of nucleation therein.
10. The device of claim 9 , further comprising two or more thin-film transistors, wherein each of said two or more thin-film transistors comprises one or more active-channel regions, and wherein each of said one or more active-channel regions comprises at least one of said two or more rectangular crystalline regions.
11. The device of claim 10 , further comprising an integrated circuit which comprises said two or more thin-film transistors.
12. The device of claim 10 , wherein said device is a liquid-crystal display device which comprises said two or more thin-film transistors.
13. The device of claim 12 , wherein said two or more thin-film transistors are pixel-controller thin-film transistors.
14. The device of claim 10 , wherein said device is a liquid-crystal display device which comprises of a pixel-driver integrated circuit which comprises said two or more thin-film transistors.
